Scope

Scope: Applicable to the inspection and testing of multi-joint modular bridge expansion devices used in highways, municipalities, and railways; Main technical content: This standard specifies the relevant test requirements for the deformation performance of multi-joint modular highway bridge expansion devices. It clarifies the technical requirements related to the deformation performance of multi-joint modular highway bridge expansion devices during tensile and compression tests, including the maximum horizontal friction force during tensile and compression tests; the uniformity of deformation during tensile and compression tests (maximum deviation value per unit and maximum total deviation value of deformation); the maximum vertical deformation deviation per unit during tensile and compression tests; and the misalignment performance (longitudinal misalignment, lateral misalignment, and vertical misalignment) under the conditions of meeting the horizontal friction force and deformation uniformity requirements. It also provides detailed regulations on the test equipment, sample requirements, test steps, calculation of measurement results, determination of results, and preparation of test reports during the test process. At the same time, an appendix provides a deformation performance record form for the bridge expansion device for reference.
